Angular 2 — 执行命令时出错:精简服务器

Question

我有这台机器，我安装了Zsh和OhMyZsh，然后我卸载了它们。

现在，当我在 Angular 2 快速入门模板上运行"npm start"时，它会返回此错误：

Error occured when executing command: lite-server
 Error: spawn /usr/bin/zsh ENOENT
     at exports._errnoException (util.js:1022:11)

npm ERR! There is likely additional logging output above.

从错误堆栈的第二行，我可以看到 Zsh 存在问题，但我无法弄清楚如何解决这个问题。

谢谢。

Answer 1

我已经使用了本文中关于类似问题的建议：Angular2 快速入门 npm start 无法正常工作

它说尝试将 package.json 中的开始从

"start": "tsc && concurrently "npm run tsc:w" "npm run lite" "

自：

"start": "concurrently "npm run tsc:w" "npm run lite" "

看看这是否适合您。

Answer 2

尝试

在快速入门目录中打开 2 个 cmd 实例：

窗口 1#npm 运行版本：观看

然后。。。。

窗口 2#npm 运行服务

它将打开浏览器窗口并运行应用程序
